I believe that what the ISO spec says is "you should use thursday
weeks", while these functions implement sunday weeks and monday weeks.
i.e. your behavior would be right for
g_date_get_thursday_week_of_year().

Though at that point, maybe g_date_get_week_of_year() taking a day of
the week argument would be appropriate.
